I can't install Nook for PC or Windows Nook! Both say that they are unavailable. B and N seem to be holding my ebooks hostage! I downloaded an old version of nook for PC which shows my books, but when I press download, it either says "remove local copy" or "We are experiencing technical difficulties at this time - please try again later. (Download: 2157)"

That's what have experienced a few days ago, but problem has been fixed now since I have downloaded Nook windows app.

I have Nook for PC set up on my Windows 10 PC. It downloaded fine even last month. When I saw this thread, I tried to download a Nook book and - yup, I'm seeing the same 2157 message! So this is very new. I know my credit card is good - checked that.

I had Nook Study before. I found it a bit of a pain at times, but I may try it again. Or, I may try uninstalling Nook for PC and re-installing, and see if that fixes the problem.

I was trying to see what works and what doesn't and here's what I came up with.

NOOK for PC doesn't work anymore.

NOOK Study starts to sign me inworks!

NOOK for Windows works for me.

NOOK for Android works on some of my devices.

The Windows app downloads books and I can remove the DRM using Calibre, BUT the key that the Calibre dialog retrieves no longer works. The NOOK Study key works, though, and even after the incomplete login, the instructions in the B&N readme from the Tools found the working key.

The Android thing appears to be related to the TLS 1.2 updates a while ago. Older devices don't work, newer ones do. Unfortunately, Android-x86, even the latest version, no longer works, so I had to use a legit Android phone. The Android app also uses the same key as NOOK Study and books can be retrieved from a rooted phone ("/data/data/bn.ereader/files/B&N Downloads/Books").

The problem with NOOK for PC is that the login is fine and the library syncs, but downloading any book with DRM fails. Samples and some indie books download, but any with DRM give a "Download: 2157" error.

This is not good on Monday I tested Nook for PC ono my windows10 tablet it worked, could download books both drm and drm free plus do all functions. Today I can no longer download drm books, but all functions still work.

Thank goodness I downloaded all my books when we first started having problems with the download links on their website. This sounds like a mess! And as someone still on a Window 7 computer, I couldn't install the app.
